In April 2013, Yarramine was engaged by Probuild to undertake rainwater quality testing at six households located in the Murphys Creek district as part of an investigation of dust impacts arising from Probuild Civil’s road repairs works along Murphys Creek Rd.

The scope of works included rainwater, roof dust, tank sludge and roadbase sampling as well as stereomicroscopy anlayses of all samples collected to compare their makeup and determine the proportion of dust attributable to Probuild Civil’s activities.
